GARPET-SWEEPER BRUSH.

Application filed November 27, 1917.

To all whom it may concern:

Be it known that I, JAMES P. N. ADAMS, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State of Michigan,have invented certain new and useful Improvements in Carpet- SweeperBrushes, of which the following is a specification.

My invention relates to improvements in carpet sweeper brushes, and itsobjects are: first, to provide a sanitary brush, or as nearly so spossible; second, to provide a brush thawill not become entangled withhair. strings, ravelings. &c. when sweeping, and, third. to provide abrush that will not become heavily loaded with dust.

I attain these objects by the construction and arrangement of partsshown in the accompanying drawing, in which Figure 1 1s a plan of mybrush with two wings thereon shown in section to more fully disclose theconstruction of my completed Wings. Fig. 2 is a transverse section ofthe brush, practically on the line 2-2 of Fig. 1. Fig. 3 is a transversevertical section of the carpet sweeper case with my brush in placetherein, showing its relative osition with the dust pans. Figs. 45 s owmodified forms of openings in the wings.

Similar reference numerals indicate similar parts throughout the severalviews.

In the construction of this brush I dispense with the use of bristles inthe brush and substitute some flexible sheet material, as rubber, intheir place. This material is made in long narrow strips, as indicatedat 2, placed in. grooves in the roller 1, as indicated in Fig. 2, andare punctured with numerous holes, 3, so that currents of air may passthrough the sheet material or wings 2. These holes are uniformlydistributed, both longitudinally and laterally of the wings. This avertsthe danger of the air passing forcibly off of the edges of the wings,and fanning the dust into a. thick cloud in the case 5, as would be thecase if the perforations were not provided, with the result that insteadof blowing the dust out from under the sweeper case, my brush willcollect all dust and force it into the Specification of Letters Patent.

pans 7, more cleanly than with the use of an ordinary bristle brush, Theuniformly smooth edges of the wings not only beat and loosen the dust inthe nape of the carpet, but carry it uniformly into the pans.

My brush is made to revolve by the action of the wheels 6 upon thefriction roller 4, on the brush roller, in the usual manner of operatingcarpet sweeper brushes.

In the construction of this brush any desired number of wings 2 may beused, but I seem to produce the best results with the use of six toeight wings.

It will be readily understood that it is not necessary to form roundpunctures in the wings, and that any other available form will answer,the desired result being to allow a large proportion of the air agitatedby the wings, when revolving rapid to pass through the Wings instead ofpassing off of the edges of the wings; as, for instance, oblong holesmay be made longitudinally of the wings, as shown in Fig. 4, orcrosswise of the wings, as in Fig. 5, or any other de sired form orpositioned holes that may be made available for the purpose stated, asindicated at 3' and 3".

An especially advantageous result growing out of this construction isthe elimination of any possibility of insects getting into the cases anddestroying the bristles, as frequently occurs with bristle brushes, especially when the sweepers are stored away in large quantities, inwarehouses, on ship board, and in kindred places. These brushes, are,also, especially adapted for sweeping, and especially for washing varnished or Waxed wooden floors, tile floors, and linoleums.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is:

In combination with a carpet sweeper brush roller, long, narrow, thinstrips of flexible material secured at one edge to the roller andradiating therefrom, and provided with numerous uniformly positionedholes through them.
